Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light:
Note 29 at Col 1:12: Notice that Paul said the Father "hath made us meet" (emphasis mine). The Lord is not going to enable us in the future. He's already done it. As Joh 1:12 says, "But as many as received him, to them gave he power to become the sons of God." The Greek word for "meet" is "HIKANOO," and it means "to make sufficient [or] render fit" (Thayer's Greek-English Lexicon, brackets mine) to partake of God's inheritance for the saints. We, as children of God, have been supernaturally enabled to manifest the blessings of our inheritance. The New International Version says "has qualified you." The ability is there; we just have to use it.
Note 30 at Col 1:12: An "inheritance" is actually an "allotted portion" (Thayer's Greek-English Lexicon). It is described as "eternal life" in Mt 19:29 - "And every one that hath forsaken houses, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my name's sake, shall receive a hundredfold, and shall inherit everlasting life" (emphasis mine). Thayer's Greek-English Lexicon describes it as "the part which one will have in eternal salvation...eternal salvation itself...i.e. the eternal salvation which God has assigned," and all the benefits and blessings of which it consists.
